EMILE FRANCKAERTS, OF SAN FRANCISCO, CALIFORNIA.

DOOR-HOLDER.

i 0 @ZZ fio/om it may concern Be. it known that I, EuILE FRANCKAERTS, acitizen of the United States, and a resident of San Francisco, in thecounty of'San Francisco and State of California, have made certain newand useful Improvements in Door- Holders, of which the following is aspecification.

My invention relates to improvements in door holders, and it consists inthe combinations, constructions and arrangements herein described andclaimed.

An object of my invention is to provide a device for holding a door inopen position, which may be readily set or released at will.

A further object of my invention is to provide means for positivelyholding a door in open position so as to prevent the closing of the sameeven when considerable force is used, but which will instantly releasewhen a release mechanism is operated, so as to permit the door to close.

A further object of my invention is to provide a door holder havingcomparatively few parts for accomplishing the above named objects, whichis cheaply manufactured, and which is not liable to easily get out oforder.

Other objects and advantages will appear in the following specificationand the. novel features of the device will be particularly pointed outin the appended claim.

My invention is illustrated in the accompanying drawing forming a partof this application, in which- Figure 1 is a face view of the doorholder as applied to a door. Fig. 2 is a sectional view through the doorand the door holder. Fig. 3 is a rear view of the door holder. Fig. 4 isa sectional view along the line 4 4 of Fig. 2, and Fig. 5 is a sectionalview along the line 5-5 of Fig. 2.

In carrying out my invention I provide a main casing 1, which is of theshape shown in the drawings. It is provided with an upper extendedportion 2 and with side lugs 3. The portions 2 and 3 are perforated soas to afford means for attaching the casing to a door.

Arranged to slide within the casing 1 is .an auxiliary casing 4, whichis hollow. The rear side of the inner casing 4 is provided with abearing member 5 having an elongated opening 6. The bearing member 5 isdove-tailed as shown in Figs. 4 and 5, to enter the grooves 1x of themain casing.

This provides means for guiding the inner casing in its movement.

Pivotally supported at the lower end of the inner casing is a stopmember 7, which bears at its lower end a resilient bu'er 8 of rubber orother suitable material. The upper end of the stop member 7 is pressedupon by a spring 9, which bears on the inner side of the member 5. Thestop 8 holds the butter 8 in position Arranged to extend transversely ofthe device are two partitions, a lower one 10 and an upper one 11. Thesepartitions are of the shape shown in Fig. 5. They are pro vided withcentral openings arranged to receive a rod 12, which is secured to a capmember 13 at the top of the auxiliary casing 4. The cap 13 is providedwith a tongue 13X arranged to enter a slot in the rear part of thecasing 4 and is held in position by means of a screw 14. A spiral spring15 bears at one end on the cap 13, and at the other end of the partition11.

A locking member 16 like that shown in Fig. 4 has a tongue 16a whichpasses through the slot in the member 5 and enters an opening in a plate17 secured to the rear side of the casing 1. The plate 17 is alsoprovided with openings arranged to receive one end of the partit-ions 10and 11. The locking member 16 passes through an open* ing in the casings1 and 4, and is provided with an integral extension 16b on the outsidethereof. The rod 12 passes through an opening 16c in the locking member16. A spring 18 normally holds the locking member 16 in such position asto cause the rod 12 to bind against the walls of the opening 16C. Theopening 16c in the locking member 16 may, however, be brought intoposition so as to permit a free movement of the rod by moving thelocking member 16 downwardly.

From the foregoing description of the various parts of the device theoperation thereof may be readily understood. The apparatus is fastenedon to the side of the door near the bottom thereof, as shown in Fig. 2.Now when it is desired to open the door and hold it open, one may placehis foot on top of the cap 13 and press downwardly. This causes thecasing 4 to slide downwardly within the casing 1, spring 15 being putunder tension. The locking member 16 is held by the spring 13 so as toprevent the retraction of the rod 12. Thus the stop member 7 is held inclose engagement with the floor,

the rubber buffer preventing the movement of the door. If there is anyattempt to move the door, the stop member will swing outwardly into theposition shown in dotted lines, eausin a rmer grip of the device on thefloor. T e stop member will thus resist any tendency to close the door.Now when it is desired to release the door, the extension 16b of thelocking member 16 is pressed downwardly either with the foot or with thefinger, thereby releasing the rod l2, which underthe iniuenee of thespring 15, raises the slidable casing 4, together with the stop member 7from the floor into the position shown in Fig. 2, thereby permitting thedoor to swing free.

I claim In a door holder, a main outer casing provided with grooves, anauxiliary Casing disposed within said auxiliary casing and slidable withrespect thereto, a bearing member arranged to enter the grooves forguiding the inner easing in its movement, a pivoted stop membersupported at the lower end of the inner easing, a spring having one endnormally pressing upon the upper end of the stop member, and the otherend bearing on the inner side of the bearing member, a pair ofpartitions having alined openings, a eentral clamping member disposedbetween the partitions and being provided with an opening, a rod Carriedby the inner auxiliary Copies of this patent may be obtained for vecents each, by addressing the Commissioner of Patents, Washington, D. C.
